한강유역에서 출토된 고구려자에 대한 一考

Abstract

The measuring systems have a basic social and political meaning in a state not only to rule the people, but also to collect tax on their people. In this meaning, the kingdom of Koguryo has a unique and specific measuring system in the history of East Asia. That was so called 'Koguryo-ja or Koguryo-chuk.' In this paper, I reviewed the measuring system of Koguryo with regard to the excavation of Koguryo-ja in Isongsanson fortress near lower Han River basin. The results are as follow: First, documents about Koguryo-ja were found in many of Japanese historical materials like Reisuikai, Rriikai, and Jyokunihongi. For example, according to the Reisuikai, Koguryo-ja was documented as a Koma-jaku, or Koma' rule. In here, Koma in Japanese means Koguryo in Korean, and jaku in Japanese means also ja in Korean. Second, archaeological materials have indicated that Koguryo has at least three measuring systems such as Anhakgung-ja, Koguryo-ja, and Nongori-ja. Anhakgung-ja was 20.0cm in length. This ruler was verified by detection of archaeological excavation on Anhak palace. woodenly made Koguryo-ja was uncovered on Isongsansong fortress. Its length is 35.6cm. Documents about Nongori-ja were found in Nongori fortress as an inscription on the rock. The length of the ruler is 47.7cm. Lastly, so far two materials of Koguryo-ja(35.6cm) were excavated in Korea and Japan. Mentioned above, one of Koguyo-ja was excavated on Isongsansong fortress in Korea, July 2000. The other was uncovered on the archaeological site of Gojitahigasi in Japan, 2001. Summarizing the results of study, although Chinese influences had permeated into Koguryo society for a time, Koguryo grew and developed their social systems including Measuring system independently. Archaeological remains firmly indicated that Koguryo had independently devised the measuring system called 'Koguryo-ja.'
